        Description copied from interface: Reader
        Locates and decodes a barcode in some format within an image. This method also accepts hints, each possibly associated to some data, which may help the implementation decode.
        Specified by:
        decode in interface Reader
        Parameters:
        image - image of barcode to decode
        hints - passed as a Map from DecodeHintType to arbitrary data. The meaning of the data depends upon the hint type. The implementation may or may not do anything with these hints.
        Returns:
        String which the barcode encodes
        Throws:
        NotFoundException - if no potential barcode is found
        FormatException - if a potential barcode is found but format is invalid
